(Vers. 24 seqq.) Then Jesus said to his disciples: If anyone wants to come after me, let him deny himself and take up his cross and follow me. For whoever wants to save his life will lose it, but whoever loses his life for my sake will find it. For what does it profit a man if he gains the whole world but loses his own soul? Whoever puts off the old man with his works (Colossians 3), denies himself, saying: Now I live, but Christ lives in me (Galatians 2:20): and he takes up his cross and is crucified to the world. But the one to whom the world was crucified follows the crucified Lord.
But what exchange will a man give for his soul? For Israel, Egypt and Ethiopia are given in exchange, and Syene (Isaiah XLIII, 3, 4): for the human soul, that alone is the retribution, which the Psalmist sings: What shall I render to the Lord for all that He has rendered to me? I will take the cup of salvation, and will invoke the name of the Lord (Psalm CXV, 3).
16:27
(Verse 27) For the Son of Man is coming in the glory of His Father with His angels, and then He will repay each according to his deeds. Peter, scandalized by the preaching of the Lord's death, was rebuked by the Lord's sentence. The disciples were provoked to deny themselves, take up their cross, and follow their teacher with a willing heart. The great terror of the listeners, and the ability of the chief apostle to instill fear in others, led to sadness followed by joy, and he said: The Son of Man is coming in the glory of His Father with His angels. Fear death, listen to the glory of the triumphant. Fear the cross, listen to the ministries of the angels. And then, it is said, he will repay each according to his works (Rom. X, 12). There is no distinction between Jew and Gentile, man and woman, poor and rich, where not persons, but works are considered.
16:28
(Verse 28.) Truly I say to you, there are some standing here who will not taste death until they see the Son of Man coming in his kingdom. He wanted to heal the terror of the apostles with the hope of promised things, saying: The Son of Man is coming in the glory of his Father with his angels. Moreover, with the authority of a judge added: and he will repay each one according to his works. The silent thought of the apostles could bear such a scandal: you now say that killing and death are coming, but what you promise to be present in the glory of the Father with the ministry of angels and the power of a judge, this will be in the future, and will be delayed for a long time. Therefore, foreseeing what the knowers of secret things could object, he counterbalances present fear with present reward. For he says: There are some of those standing here who will not taste death until they see the Son of Man coming in his kingdom; so that the manner in which he will come afterwards may be shown to you at the present time, because of your unbelief.
17:1
(Chapter 17 - Verse 1) And after six days, Jesus took Peter and James, and John his brother. Why Peter, James, and John are separated from the others in some places in the Gospels, or what privilege they have over the other apostles, we have frequently discussed. Now it is asked how he assumed them after six days, and led them to a high mountain apart: since the evangelist Luke mentions the number eight (Luke 9). But the answer is easy, because here the intermediate days are placed, the first and the last are added. For it is not said: After eight days Jesus took Peter, and James, and John; but on the eighth day.
He leads them to a high mountain apart. To lead the disciples to the mountains is part of the kingdom. They are led apart, because many are called, but few are chosen (Matthew 20:16 and 22:14).
17:2
(V2.) And he was transfigured before them. Just as he will be at the time of judgment, so he appeared to the apostles. But when it says, 'He was transfigured before them,' no one can think that he lost or abandoned his original form and appearance, or that he took on a spiritual or aerial body. Rather, the evangelist demonstrates how he was transformed, saying.
And his face shone like the sun, and his garments became white as snow. Where the splendor of his face is shown and the whiteness of the garments is described, substance is not taken away but glory is transformed. His face shone like the sun. Certainly the Lord was transformed into that glory in which he would come afterwards in his kingdom. Transformation added splendor, it did not take away his face. Even if his body was spiritual, were the garments also changed, which were so white that another evangelist said: Such as no fuller on earth can make. But what the lightning can do over the earth is corporeal, and subject to touch, and not spiritual and airy, which deceives the eyes, and can only be seen in a mere illusion.
17:3
(Verse 3.) And behold, Moses and Elijah appeared to them, talking with him. When the scribes and Pharisees tested him, seeking signs from heaven, he did not want to give them, but refuted their wicked request with a prudent response. But in order to increase the faith of the apostles, he gives a sign from heaven, with Elijah descending from where he had ascended, and with Moses rising from the dead. This is also commanded to Ahaz through Isaiah, to ask for a sign from above or from below (Isaiah 7 and 2 Kings 2). For what was said: Moses and Elias appeared to them, speaking with him; and in another Gospel it is reported that he announced what he would suffer in Jerusalem (Luke IX): The law and the prophets are shown, who announced with frequent voices both the passion of the Lord and his resurrection.
17:4
(Verse 4.) But Peter, replying, said to Jesus: Lord, it is good for us to be here. He who had ascended to the mountains does not want to descend to earthly things; but always to persevere in the lofty things.
If you wish, let us make here three tabernacles: one for you, one for Moses, and one for Elijah. You are mistaken, Peter, as another evangelist testifies. You do not know what you are saying. Do not seek three tabernacles, for there is one tabernacle of the Gospel, in which the Law and the Prophets are recapitulated. But if you seek three tabernacles, do not compare servants with the Lord, but make three tabernacles: indeed, one for the Father, and the Son, and the Holy Spirit; so that, since they are one divinity, there may be one tabernacle in your heart as well.
17:5
(Verse 5) While he was still speaking, behold, a bright cloud overshadowed them. And behold, a voice from the cloud, saying, This is my beloved Son, with whom I am well pleased; listen to him. Because he had asked foolishly, he does not deserve an answer from the Lord, but the Father speaks for the Son, so that the word of the Lord may be fulfilled: I do not testify of myself, but the Father who sent me, he testifies of me (John 5:37 and 8:18). But the cloud is seen as both bright and shadowed: like those who sought the tabernacle from the fleshly leaves or tents, they would be covered by the shadow of the bright cloud. Moreover, the voice of the Father speaking from heaven is heard, which also testifies to the Son; and through Peter, with error removed, teaches the truth: even through Peter to the other apostles. This is, he says, my beloved Son: to him the tabernacle must be affixed, to him obedience must be given. Here is the son, those slaves are: Moses and Elias themselves must prepare a tabernacle for the Lord with you in the innermost depths of their heart.
17:6
(Verse 6.) And when the disciples heard this, they fell on their faces and were exceedingly afraid. They were terrified for three reasons: either because they realized they had made a mistake, or because a shining cloud had covered them, or because they had heard the voice of God the Father speaking. For human frailty cannot bear the sight of greater glory and, trembling in mind and body, falls to the ground. The more one seeks greater things, the more one will collapse into lower things if one does not know one's own measure.
17:7
(Verse 7) And Jesus came and touched them. Because they were lying down and unable to rise, he kindly approached and touched them, so that fear would flee with the touch and their weakened limbs would be strengthened.
And he said to them: Rise up, and do not be afraid. He who healed with his hand, heals with his command. Do not be afraid. First, fear is expelled, so that later, knowledge may be given.
